A couple weeks ago when Apple Watch Series 3 cellular reviews were published by select media outlets, reviewers noted a bug caused the watch to fail to connect to LTE networks, but rather hang onto unknown Wi-Fi networks instead.
Apple promised a fixed was coming, and now it is here as watchOS 4.0.1 has been released via an over-the-air update, build 15R654, for 38mm and 42mm Apple Watch Series 3 LTE owners. The release comes two weeks after watchOS 4 was first released.
To update your Apple Watch Series 3 LTE, on your iPhone, launch the Apple Watch iOS app, then go to:
General > Software Update
The update will appear over-the-air, where you’ll be able to install it.
Apple Watch Series 3 cellular models start at $519 CAD, with Bell supporting wireless capabilities at launch, but Telus is set to follow shortly with a December 1 launch (they deleted their tweet it seems).
